Flatbush diabetes: A report of two cases and a review of the literature

Abstract

Type 2 diabetes is an endocrine and metabolic disorder appearing with insulin resistance and impaired beta cell secretory function. Type 1 diabetes is characterized by the autoimmune destruction of pancreatic beta cells, which leads to absolute insulin deficiency. Diabetic ketoacidosis is considered a cardinal feature of type 1 diabetes. A number of studies have demonstrated that diabetic ketoacidosis also occurs in subjects with type 2 diabetes. Such patients are classified as idiopathic type 1 diabetes, type 1B diabetes, Flatbush diabetes or ketosis-prone type 2 diabetes. The aim of our study was to present two patients, who were diagnosed with ketosis-prone type 2 DM, as well as to discuss the subject in the light of the extant literature and to be able to make general recommendations.
